Which statement is true regarding the outcome of mitosis?

Creates four unique daughter cells

Involves two rounds of cell division

Produces gametes with half the chromosome number

Results in two identical daughter cells (correct)

What is a characteristic of meiosis?

Results in two daughter cells with genetic diversity

Results in four unique daughter cells (correct)

In what way does mitosis differ from meiosis?

Mitosis divides once producing two identical daughter cells; meiosis divides twice producing four non-identical cells. Signup and view all the answers
